M.O.O.D.S. transports players to a future where humans have abandoned Earth, leaving robots called “mechs” behind. With time, these mechs have evolved into self-aware entities and even created a civilization of robots. To emulate their creators, mechs develop the Moods Modules, enabling them to experience emotions. This newfound emotional capacity leads to the formation of hostile factions. Players will join a group of peaceful mechs on a mission to restore order by rebooting the mech lords, encountering friendly bots, and undertaking various quests along the way.
